I have a 16 day old baby girl. For the past 2 days she has suddenly become extremely fussy. She is refusing to sleep in her Moses basket and cries when we put her down. She just wants to be held. Previously she would sleep for at least 2 hours in the basket. She is also suddenly very hungry . She is mix feeding bottle and breast. Normally every 2-3 hours but now once she finishes a feed she is still hungry 10 mins later. She keeps crying and we don't know what to do. Nappies are normal.
